PHP中用于迭代数组的For循环在第一个循环中起作用，但在第二个循环中不起作用 - My For loop in PHP used to iterate an array works on the first loop, but not the second

My For loop in PHP used to iterate an array works on the first loop, but not the second

if (isset($_GET['q'])){$q = $_GET['q'];

              //variables
              $sql = "SELECT * FROM products WHERE product LIKE '%$q%' OR search LIKE '%$q%'";
              $result = $conn->query($sql);

              //check database
              if($result->num_rows > 0){        
                while ($row = $result->fetch_array()){
                  $product = $row['product'];
                  $productImage = $row['product_image'];
                  $price = $row['price'];
                  $seller = $row['seller_name'];
                  $sellerImage = $row['seller_image'];
                  $desc = $row['description'];
                  $search = $row['search'];
                  $console = $row['console'];
                  $array = array($product, $price, $productImage);
                  $arrayDesc = array($desc, $sellerImage);

                  if (preg_match('/Game/', $seller)){                    
                    for ($num = 0; $num < 3; $num++) {
                      echo '<div class="tile col-md-4 col-sm-3">';
                      if($num == 0){
                        echo '<div class="tileTitleBox"><h4>' . $array[$num] . '</h4></div>';
                      }
                      if($num = 1){
                        echo '<p class="price">' . $array[$num] . '</p>';
                      }
                      if($num = 2){
                        echo '<img class="tilePic" src="' . $array[$num] . '"/>';
                      }
                      // if($num = 3){
                      //   echo '<div class = "desc"><p>' . $array[$num] . '</p></div>';
                      // }
                      echo '</div>';
                    }//For Iteration Loop - TILE
                    for($count = 0; $count < 2; $count++){
                      echo '<div class="tile-description col-md-4 col-sm-3 hidden">';
                      if($count == 0){
                        echo '<div class="desc"><p>' . $arrayDesc[$count] . '</p></div>';
                      }
                      if($count == 1){
                        echo '<img class="sellerImg" src="' . $arrayDesc[$count] . '"/>';
                      }
                      echo '</div>';
                    }//end for loop - TILE-DESCRIPTION

如你所见，我有一个for循环创建"tile"，第二个for循环创建"tile-description"。第一个可以很好地创建一个类为"tile"的div，其中剩余的内容被加载到div中。但是在第二个for循环中，"desc"dev和"sellerImg"div是分开的。循环需要多次遍历数组。

所示波形:你可以看到"Tile"div包含"tileTitleBox"， "price"answers"tilePic"。但隐藏的"瓦片描述"分为两部分。

@sam-dufel正确地指出你重写了迭代器

if($num = 1){

但实际上你不应该在这里使用任何循环:

  echo '<div class="tile col-md-4 col-sm-3">';
  echo '<div class="tileTitleBox"><h4>' . $array[0] . '</h4></div>';
  echo '<p class="price">' . $array[1] . '</p>';
  echo '<img class="tilePic" src="' . $array[2] . '"/>';
  echo '</div>';
  echo '<div class="tile-description col-md-4 col-sm-3 hidden">';   
  echo '<div class="desc"><p>' . $arrayDesc[0] . '</p></div>';
  echo '<img class="sellerImg" src="' . $arrayDesc[1] . '"/>';
  echo '</div>';
